Accepted answer
To avoid disrupting your existing code, you can do something like this in Form2:

Form1 f1 = (Form1)Application.OpenForms["Form1"];
DataGridView dgv = (DataGridView)f1.Controls["dataGridView1"];
Button btn1 = (Button)f1.Controls["button1"];
Button btn2 = (Button)f1.Controls["button2"];

You can now control the DGV and buttons from Form2 using the 'dgv' , 'btn1' and 'btn2' references.

Perhaps I misunderstand what you need to do and since you already have an answer I won't spend time on this but it seems to me that one possibility would be to make a UserControl from one or both forms.

Doing it the other way around should be easier, as you're presumably opening form2 from form1:

// add this private field to form1
private Form2 f2;

// in method where you open form2, something like:

f2 = new Form2(); // assign reference to field, f2, not to a local variable
f2.Show();

// in some other method in form1

Button btn1 = (Button)f2.Controls["button1"]; // assuming form2 has a button1
btn1.PerformClick(); // or whatever you want to do
